I cut and spliced into the single red wire near the injectors. On your car, if you follow the harness from the injectors, upstream, you come to a large connector. On one side of the connector is the red/wht wire and the other side is the red wire, shown in the original wire diagram I posted, near the IAC valve. Shown here, the red/wht wire comes from the PCM Power Relay inside the CCRM, which is fed by the 30A fuse. The 30A fuse supplies power to the 10A Inj fuse and a lot of other stuff. I did not want to risk having a SES code pop on me, so I just cut and spliced.
